2023 ‘smashes’ records
RECORD-SHATTERING: 2023 “smashed” the record for the hottest year by a large margin, reported the Guardian. The newspaper said on Tuesday that, according to the EU’s Copernicus Climate Change Service, 2023 was 1.48C hotter than pre-industrial times. This is 0.17C higher than the last record set in 2016 – “marking a very large increase in climate terms”, according to the Guardian. And today the record was confirmed by the UN’s World Meteorological Organization, which has just published the findings of six leading climate datasets.
CHARTING CHANGE: In its coverage of the data, BBC News produced a number of charts and figures illustrating the path of global warming. Its analysis showed that almost every day since July has seen a new global air temperature high for the time of year. Meanwhile, the Independent published a feature examining whether 2024 could be even hotter than 2023.
STATE OF THE CLIMATE: Carbon Brief has just published the last of its quarterly state of the climate updates for 2023. It explains that 2023 was the warmest year “by a large margin”, at between 1.34C and 1.54C above pre-industrial levels across different datasets. Last year was also the warmest on record for ocean heat content, which increased notably between 2022 and 2023.
UK MP quits over fossil fuels
‘TRAGEDY’: The UK’s former energy minister Chris Skidmore quit as an MP in protest at the government’s plans to drill for more oil and gas in the North Sea, the Financial Times reported. In his resignation letter, Skidmore said it was “a tragedy that the UK has been allowed to lose its climate leadership” under prime minister Rishi Sunak, according to the newspaper.
BILL DELAYED: Skidmore quit over the government’s offshore petroleum licensing bill, which aims to “maximise” new oil and gas production, the FT said. The bill was due to be read in the House of Commons this week, but ended up being postponed, the Times reported. BBC News reported that Sir Alok Sharma, the Conservative MP and COP26 president, said he would vote against the bill, calling it “a total distraction” which reinforces the idea the UK is “not serious” about tackling climate change.
Renewables on the rise
RECORD RENEWABLES: A boom in Chinese solar power drove another record-breaking year of renewables growth in 2023, according to a new International Energy Agency (IEA) report covered by Carbon Brief. The world is now on track to build enough solar, wind and other renewables over the next five years to power the equivalent of the US and Canada combined, according to Carbon Brief’s analysis of the findings.
UK SOLAR: Along with the increase in global renewable capacity, there has been continued growth in low-carbon upgrades on UK homes, with solar and heat pumps driving record installations in 2023, according to separate Carbon Brief analysis.
Around the world
- US COAL DROP: US emissions fell by 1.9% in 2023, largely due to coal declining to its lowest level in 50 years, the New York Times reported. By contrast, US oil and gas production is set to hit a record in 2024 and 2025, said the Financial Times.
- ‘A LA CARTE’: Saudi Arabia’s energy minister has claimed that the headline COP28 agreement to transition away from fossil fuels is just one of several “choices” on an “a la carte menu”, reported Climate Home News.
- WAR EMISSIONS: Israel’s assault on Gaza since 7 October has produced more greenhouse gas emissions than 20 of the world’s most climate-vulnerable countries create in a year, according to new analysis covered by the Guardian.
- GERMANY PROTESTS: Farmers took to the streets of Berlin to protest against the German government’s decision to cut agricultural subsidies, Deutsche Welle reported.
- DEEP SEA MINING: Norway has become the first nation to approve commercial deep-sea mining, opening up a vast area of the Arctic to the extractive practice despite warnings from scientists, Mongabay reported.
- OFFSETS CONTROVERSY: The first-ever carbon-offset exchange under a new Paris Agreement mechanism, involving Switzerland buying credits for the rollout of electric buses in Thailand, is facing integrity questions, Climate Home News said.
40%
The proportion of North Sea oil and gas licences in UK waters owned by foreign companies and investors, according to EnergyMonitor.
Latest climate research
- A new research paper in Nature Climate Change presented a “conceptual framework” for considering the role of justice within climate research.
- The presence of urban green space is associated with “significantly lower rates of violent crime committed outside”, according to an International Journal of Biometeorology study conducted in Australia.
- A pair of studies in the Journal of Climate delved into an “exceptional heatwave” in east Antarctica in 2022, which brought “widespread 30-40C temperature anomalies across the ice sheet”.

Captured
A record 42 editorials opposing action to tackle climate change were published by UK newspapers in 2023, according to new Carbon Brief analysis. Written almost exclusively by right-leaning papers, these editorials called for delays to UK bans on the sale of fossil fuel-powered cars and boilers, as well as for more oil-and-gas production in the North Sea, according to the findings. In response to such demands, prime minister Rishi Sunak performed a “U-turn” in September on some of his government’s major net-zero policies.
Spotlight
Investigating Antarctica’s colossal icebergs
This week, Carbon Brief speaks to Dr Oliver Marsh, a glaciologist who is principal investigator of a British Antarctic Survey (BAS) mission currently studying iceberg calving events at Antarctica’s Brunt ice shelf (pictured).
Carbon Brief: Can you please explain what fieldwork you are currently working on?
Dr Oliver Marsh: We are drilling ice cores to collect ice samples from the Brunt ice shelf. These will be brought back to Cambridge [where BAS is located] and University College London (UCL) in order to test their physical and chemical properties. We are also setting up seismic and GPS equipment to monitor fracture growth and strain rates on the ice shelf. We will then link the properties of the ice to the behaviour of the fractures.
CB: What do you hope to find out by conducting this fieldwork?
OM: We are interested in the mechanism and timing of crack growth leading to iceberg calving [where chunks of ice break off from the front of a glacier]. In particular, we want to understand how changes in ice properties change calving rates. The ice shelf we are working on has a well-documented history of crack growth, with two large calving events in the last three years, and the new information we gain from precise laboratory measurements will help us to understand how – and under what conditions – fractures occur in the lead-up to these calving events.
CB: What are the biggest hazards with conducting fieldwork on the Brunt ice shelf?
OM: The Brunt ice shelf is a good location to monitor fracture growth due to its dynamic behaviour. This means there are rifts and other cracks in the ice that can be hazardous for travel. These cracks are heavily monitored with a suite of geophysical instruments, including ground-penetrating radar, GPS and satellite data, and precautions are taken when moving around. Fieldwork in Antarctica also has significant hazards associated with the weather, for example, strong winds and wind chill.
CB: How is climate change affecting iceberg calving events in Antarctica?
OM: Calving occurs as a normal process of ice loss from the continent. But, as it occurs in discrete events and very infrequently for some ice shelves, it is difficult to determine whether rates are changing from a short satellite record. Other fracturing processes, such as hydrofracture and ice shelf collapse, are linked to both ocean and atmospheric warming, so it is possible that calving rates may increase in the future.
CB: What would be the implications of accelerated iceberg calving for the climate and ecosystems?
OM: Increased calving is likely to weaken ice shelves that fringe the continent and support the glaciers inland. This can help to speed up glacier flow and ice loss to the ocean, contributing to sea level rise. An increase in the volume of icebergs may also cause issues for ecosystems, particularly in areas where icebergs ground on the ocean floor, blocking foraging routes for penguins and seals, for instance.

Some things are too precious to risk. And Scott Reef is one of them.
Today, we’re launching a bold new campaign starring iconic Australian actor Michael Caton and a green sea turtle named Sandy to rally Australians behind one simple message: Flip off Woodside to save Scott Reef.
Off the coast of Western Australia, Scott Reef is one of Australia’s most extraordinary marine environments. It is home to vulnerable green sea turtles, endangered pygmy blue whales and thousands of other marine species.
Each year, one thousand endangered green sea turtles return to Scott Reef to nest. It’s where they lay their eggs. It’s where baby turtles hatch. It’s where they make their first brave dash from the sand to the ocean. It’s their home.
But this remarkable ecosystem is under threat from Woodside’s plans to drill for gas, with up to 57 toxic wells proposed around the reef.
Turtles can’t speak up for their home, so we’re asking Australians to make their voices heard instead.
From one Aussie icon to another
At the heart of our new campaign is an iconic Australian voice, Michael Caton. Caton is using his voice to speak out for, what will soon be, another Australian icon – Scott Reef.
In a cinematic courtroom showdown, Caton lends his unmistakable voice to one of Scott Reef’s most vulnerable inhabitants: a green sea turtle fighting to protect her home from corporate destruction.
As Sandy the turtle defiantly flips her flippers at Woodside, Caton delivers a message that every Australian can get behind.
“Some things are too precious to risk.”
Because when it comes to protecting our natural environment, sometimes being polite just isn’t enough.
Turning a gesture into a movement
We’ve launching a campaign designed to do more than grab attention. We want to turn public concern into meaningful action.
The idea is simple: flip off Woodside and make sure our political leaders know exactly where Australians stand.
We’re calling on people across the country to share the campaign, get involved on social media and, most importantly, tag their local MPs.
We need Environment Minister Murray Watt and Prime Minister Anthony Albanese to hear loud and clear that Australians want Scott Reef protected, not sacrificed for another gas project.
China’s carbon dioxide (CO2) emissions fell by 3.1% in the third quarter of 2026, as the Hormuz crisis continued to hit oil demand and coal use also dropped.
This guest post is by:
Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air
This was the largest quarterly reduction since the 2022 Covid lockdowns and means that China’s CO2 emissions have now fallen by an estimated 0.5% in the year to date.
The new analysis for Carbon Brief, based on official figures and commercial data, shows that coal use fell by 3% year-on-year in the third quarter of 2026, while oil was down 4%.
The main drivers were a fall in power-sector coal consumption, a continued sharp reduction in transport oil consumption and slowing growth in the coal-to-chemical industry.
The sharp decline in China’s CO2 emissions extends a “flat or falling” trend that began in March 2024 and has now lasted more than two years, as shown in the figure below.
The outlook for China’s CO2 emissions depends on the balance between rising energy demand, clean-energy growth and the government response to a GDP slowdown.
Decline drivers
Key drivers of the fall in CO2 in the third quarter of 2026 included a 3.3% drop in coal-power generation, after demand growth slowed and the amount of “wasted” wind and solar fell.
Power generation from solar, wind and nuclear increased by 110 terawatt hours (TWh) year-on-year, more than twice as much as the growth in total electricity demand. This added clean-power generation equal to Germany’s total power output in the same time period.
The fall in coal-power output and CO2 emissions came despite the fact that China continues to build new coal-power capacity at near-record rates. This means that average running hours for coal plants are falling even faster than total generation, eroding their profits.
Meanwhile, transport oil consumption continued to fall sharply, down 9% year-on-year in the third quarter of 2026. Electric vehicles (EVs) continued to gain market share, hitting a record 67% of passenger car sales and 50% of heavy trucks in September.
The amount of electricity used by EVs grew by 53%, much faster than the number of EVs on the road, showing increased usage of the existing fleet in preference to fuelled vehicles.
Elsewhere, growth in the coal-to-chemical industry continued to slow down in the third quarter of 2026. The sector has been a key source of emissions growth, but high coal prices have weakened profitability and higher output prices hurt downstream demand.
Finally, CO2 emissions from cement and steel production continued to fall in the third quarter, as the contraction in construction volumes accelerated.
Outlook for emissions
Energy consumption growth has been falling after a period of exceptionally high growth during Covid, while clean-power growth has been robust.
This makes it likely that the growth in clean-power generation will exceed total energy demand growth this year, maintaining the structural fall in fossil-fuel use.
Looking ahead, this balance also relies on progress in removing barriers to new solar and wind power being added to the grid, which result in some clean electricity being “wasted”.
The recent slowdown in energy demand growth is partly – but not fully – explained by exceptionally mild weather in the third quarter.
Another key factor is weaker GDP growth. Since reported GDP growth remains within target, however, there is reduced pressure for further stimulus policies.
The focus of the economic stimulus announced to date is “six networks”, which includes the power grid and the transportation network.
These networks are highly relevant for energy and emissions – and they are already covered by policies that emphasise “green” and zero-carbon solutions.
